Quitting smoking can significantly reduce the risk of coronary heart disease and other health problems. Dr. Mai Manh Tam from the Department of Respiratory Medicine at Tam Anh General Hospital in Hanoi explained that smoking is the leading cause of lung cancer and respiratory diseases such as COPD and pulmonary fibrosis. Despite being aware of these risks, some smokers continue to use tobacco, believing that not everyone who smokes gets sick.
Nicotine in cigarettes stimulates the production of adrenaline, causing the heart rate to increase and blood pressure to rise. Carbon monoxide in cigarette smoke reduces the amount of oxygen transported by red blood cells, leading to fatigue and weakness. After 12 hours of not smoking, carbon monoxide levels return to normal. Smokers often experience coughing and increased phlegm production, which improves after quitting smoking for 1-9 months.
The risk of coronary heart disease is significantly reduced after quitting smoking for a year, as the progression of arteriosclerosis caused by CO exposure decreases. The risk of heart attack and coronary artery disease is also reduced over time, with the risk returning to that of a non-smoker after 15 years of quitting. Quitting smoking reduces the risk of various cancers, especially lung cancer, and improves overall health.
Despite the benefits of quitting smoking, many find it difficult due to nicotine cravings and withdrawal symptoms. Doctors can prescribe medication to help with quitting, and it’s important for family, friends, and colleagues to provide support and encouragement. Understanding the long-term health benefits of quitting smoking can motivate individuals to stay committed to quitting.
In conclusion, quitting smoking is a crucial step towards maintaining good health
